Citroën berlingo 2012 engine fault light

Hello. My vehicle, I took my friend's uncle to the industry for the complaint of engine water loss at 150 thousand km. I have cracked the thermostat. I bought the original thermostat. After I had it done, the engine fault lamp started to light and the warning was lit with the danger of clogging of the particle filter.I went to put the 900 TL particle cleaning and liquid.It went to the fault, and then there was no problem when the car was cooled. They say there is no such possibility, just because they have pieces. Later, when they looked at the fault, P1352, P0266, P0263, P0269 gave me the FAILURE codes, this master put me diesel filter and injector cleaner in the tank and said that my injectors need to be maintained, I do not understand for how many days, but the problem is not solved. I went to Istanbul injector last day, you will leave the car that he told me for 1 day. I wonder if I should disassemble the thermostat and have someone else do it again, I want to get your ideas, I would be glad if you help me on this issue.

First of all, welcome to us. After a tormostat replacement, these errors are very strange, there is a part that is wrongly installed in the operations done, not every master, but not every master, you need to find a master who knows the peugeot engines and has the original software. Judging by the error codes, 1352 is usually caused by glow plugs. others are unfortunately injector error. highly likely to be saved with a repair kit.
